Eczema is a skin condition where the skin gets red or inflamed die to an allergic reaction. In certain cases it may be hereditary. The exact cause is not known though it is highly contagious. It cannot be cured but can be managed.
One of the few things to you can do to control your rash is to stay away from things that you may be allergic to. Dust, synthetic fibers and fur from house pets are your worst enemy. Keep your pets away from your bedroom and never let them sleep on your bed. Even though you may dust your linen traces of fur will still be evident. Wash your hands only when absolutely necessary as certain soaps tend to cause the reaction. Use a natural antibacterial soap-free handwash instead.
Wear cotton clothes as far as possible as wool and synthetic fibers tend to cause a rash with sensitive skin. Use cotton linen and towels as well. Even synthetic curtains may spread the rash as they brush against your skin as your walk between them.
Use mild glycerin soaps during your bath or one that has a high moisturizing content. Keep your baths short and do not use hot water as it strips the moisture from your skin. Petroleum jelly like Vaseline helps to moisturize your skin as it a cost effective option as well.
Do not scratch your body as the rash will spread to different parts of your body.
Your diet should not have traces of shellfish like crabs, oysters and prawns. Stay away from extremely starchy foods and fried foods. Junk foods should always be minimal. Drink lots of water to keep your skin hydrated always. Stay away from coffee and teas as they tend to dehydrate you. Drink fruit juices if you are not particularly keen about water. Sugarcane juice is a good cure for your rash and has a very high water content.
Keep away from extreme conditions like heat and cold. Go to the beach only if it is a must. Wash off all traces of sand immediately after returning from the ocean as the sand will tend to aggravate your skin condition. Always protect yourself from the sun as sweat may increase the rash.
Remember that you are the only person that can control your condition so continue your regime even after the condition dissolves itself in order to prevent it from returning or spreading
